One favorite family myth on my father's side is that El Sakakra, the village where they are from, has a lot of people who are descendants of Omar ibn al-Khattab عمر بن الخطاب who was the second Caliph after the prophet.

Al-Maqrizi's المقريزي in Al-Bayan wa Al-I'rab الببان و الاعراب  quotes one nassabah (genealogy expert) saying:

وأما العُمَريّون الذين بأرض مصر فإنهم ينسبون إلى عبد الله بن عمر بن الخطاب رضى الله تعالى عنه. وقال الشريف محمد بن أسعد الجواني النسابة: وهم يكذبون في ذلك لأن أنسابهم لاتتصل به وقد لقيت منهم جماعة وعرفتهم كذبهم بطريق علمته.

All the present Baheyeldins are direct descendants (sons, grandsons, and granddaughters) of Mohamed Baheyeldin.

Mohamed Baheyeldin was the eldest son of Ahmed Mohamed Abdallah Mohamed Ali (El Gada') El Hosseini Omran, in Arabic: محمد بهى الدين احمد محمد عبدالله محمد على الجدع الحصيني عمران. The Hosseini name is spelled الحسينى or الحصين.

Here is a simple family tree.

Baheyeldin's Father

Ahmed was born in 1910 in El Sakakra, and was a teacher, then a school principal, then education inspector.

El Sakakra السكاكرة is a village about 3 kilometers north east of Hehia ههيا (also Hehya), which is the center (Markaz) to which Shersheima belongs. Hehia is about 15 kilometers north east of El Zaqaziq الزقازيق , the capital of the governorate of El Sharqeyya (Sharkeya or Sharkeyya الشرقية).

In the 1960s, it had only 2,100 people, and by the early 21st century, it has 6,000 to 7,000 people. 

Shersheima شرشيمة (or Shershema) is a twin village of El Sakakra, with a drainage canal separating them, which has been filled now.
